Finished dormer wall flashing.

New red cedar siding is installed. Painting to come later. 

The original metal roof to wall flashing. The original galvanized metal flashing had been installed on the outside of the wall trim. Fairly well rusted and loose in some areas it's useful lifetime was almost over.

After removing the original slate roofing and galvanized roof flashing, new underlayments and slate has been installed. A horizontal line was marked on the corner trim where the roof plane will intersect, and then cut the width of the trim so a new piece of flashing could be slid behind the trim and over the slate roofing. The vertical cut was extended upward to accept a taller shingle tin flashing.

New dormer apron flashing made of copper to last as long as the slate without maintenance. Half inch hem on the bottom edge. 3" bend up the wall and 5" on the roof.

Installed from the side, the apron flashing is slid behind the corner board all the way to the outer edge of the slate.

View from the side. Notice the upper chalkline? a slight mistake in measuring caught before installation went too far. The apron flashing has been drilled and nailed to the roof with a copper roofing nail.

Side flashing step tin installed. The copper tin extends past the outside corner board about 3/4" and 1 1/2" past the dormer wall sheathing. The flashing tin has been cut at an angle from the bottom to the corner board and then up flush with the outside face of the corner board.

The tin is nailed at the outside upper corner with copper roofing nails.

Dormer apron and shingle step flashing tin installed.

Second slate and copper flashing tin installed.

The water marks are from a patina solution. The homeowner asked that the copper be darkened to a semi aged color during installation.
